iPhone 16 Pro: Diagnosing single 'Panic Full LLC' error?

Panic Full iphone 16

Hi everyone! I've had a bad experience. I bought an iPhone 16 Pro, and after four months it turned off and showed a "Panic Full LLC error from CPU0" error. I contacted the store where I bought it, and they said they could send it to Apple for diagnostics and repairs. The problem is that the error only occurred once, and a reset will clear it. Can they diagnose it?

If you have the Apple Support app on your iPhone, you can use that and Apple can run diagnostics remotely.

You likely have the app on your phone, but if you don't, I provided a link for you to go the App Store and download it. Open the App and follow the directions to start a session with Apple Support.

Can you explain how to do this? Or provide a link to a resource that will tell you about it?
